Evidence that FGFRL1 contributes to congenital diaphragmatic hernia development in humans.

Am J Med Genet A 2021 03 14;185(3):836-840. Epub 2021 Jan 14.

Department of Molecular and Human Genetics, Baylor College of Medicine, Houston, Texas, USA.

Fibroblast growth factor receptor-like 1 (FGFRL1) encodes a transmembrane protein that is related to fibroblast growth factor receptors but lacks an intercellular tyrosine kinase domain. in vitro studies suggest that FGFRL1 inhibits cell proliferation and promotes cell differentiation and cell adhesion. Mice that lack FGFRL1 die shortly after birth from respiratory distress and have abnormally thin diaphragms whose muscular hypoplasia allows the liver to protrude into the thoracic cavity. Read More
